Wasn't sure where to post, but since I'm an active airline pilot this seems reasonable.

So I want to get checked out in a 172 or the like with the intent of taking my teens up in a light airplane for the first time (just for the experience of it, not to interest them in this career I think, but that's another discussion). I was considering sitting in on an AOPA Rusty Pilot Seminar (free to members, and I am) as I admittedly have lost currency in all things VFR and/or GA. Has anyone done this and is it valuable?

Any recommendations for airplane rentals and instructors in the NW DFW area are welcomed too. Other wisdom/tips will be appreciated as well
